The GRACO 16H491 is a threaded adapter designed to connect equipment with a 1/2 inch NPT (National Pipe Thread) female port to a 1/4 inch NPT male port. Its material is not specified in available sources, but it is engineered for robust performance in fluid handling systems. This adapter ensures efficient equipment functionality by enabling seamless transitions between different pipe sizes within GRACO fluid management systems.

Key Features:

• Adapter
• 1/2 NPT to 1/4 NPT
• Compatible with GRACO equipment requiring a transition from 1/2 NPT to 1/4 NPT
• Facilitates seamless transition between pipe sizes
• Ensures efficient equipment functionality
• Reliable connection for fluid transfer

Applications:
Used in fluid handling and transfer systems where a transition from 1/2 inch NPT to 1/4 inch NPT is required, such as in lubrication, paint, or maintenance equipment.

Installation Notes:

• Using genuine GRACO parts ensures optimal fit, performance, and safety in fluid handling systems.
• Ensure threads are clean and free of debris before installation
• Apply appropriate thread sealant as recommended by GRACO
• Hand-tighten before using a wrench to avoid cross-threading
• Check for leaks after installation
• Regularly inspect the adapter for wear or damage
• Replace if any signs of leakage or thread damage are present
